Let's see if I remember this properly.  v35 pre-release, 783 commits
since the v35-Pre tag was created, build at commit hash 5762763d2a.
This is what you would expect from a source build.

Same

Version 35.0 (not true, its a pre-release), master branch, build date
20250205, git commit 4c4ec5e0, followed by ubuntu stuff.

That's odd.  Maybe you need to fetch tags?  Try "git fetch -t".

No idea why the deb packaging numbers things like that.  The name is
typically built from what data can be found from git and from the
filesystem.  You can look at mythtv/version.sh or the
mythtv_find_source_version function in cmake/SourceVersion.cmake to see
how the sausage is made.

Thanks, I thought it might be hard to straighten the number out on what I had, so I used timeshift to restore back to just before I built mythtv the first time and this time I built using cmake and got the right numbering MythTV Version : v35-Pre-784-g665b315a3b


So now I just need to restore the database etc. All the recordings are on a separate drive.

I wonder if you had the backend installed in two places, like /usr/bin and /usr/local/bin.


Not sure how you git the versions (mythbackend.log, git describe, dpkg -l |grep mythbackend
or mythbackend --version).


This would have shown multiples: sudo updatedb && locate --regex "bin/mythbackend$"
